Cavitation in solids is the sudden formation and expansion
of cavities in their interior in response to large triaxial loads.
The first experimental studies in elastomers are due to
Gent & Lindley [1]}, who also theoretically estimated the hydrostatic load for rupture
by solving the non-linearised equilibrium equations for
an infinitely thick elastic shell under the assumption of radial symmetry.
The first analysis of the evolution of a cavity (beyond its nucleation) was due to Ball [2]};
he showed that the one-parameter family of deformations
\( u(x)=\@root n \of {|x|^n+L^n} \frac{x}{|x|},\quad L\ge 0,\quad n=2,3\)
